Answer;
The tremors of Parkinson's disease
An undersupply of dopamine is most closely linked to the tremors of Parkinson's disease.
Step-by-step explanation;
-Parkinson's disease is primarily caused by low and falling dopamine levels. A person with Parkinson's has abnormally low dopamine levels.
-When 80 percent of dopamine is lost, PD symptoms such as tremor, slowness of movement, stiffness, and balance problems occur. Dopamine-generating cells, known as dopaminergic neurons (types of nerve cells) in the substantia nigra part of the brain may have died.
